A commuter owns two cars. One is a compact and the other is a standard model. About 3 of the time 4 he uses the compact to travel to work and about - of the time the larger car is used. When he uses the compact car, he usually gets home by 5 : 30 P.M. about 75% of the time. If he uses the standard sized car he gets home by 5 : 30 P.M. about 60% of the time. If he gets home by 5 : 35 P.M., what is the probability that he used the compact car?
